Question about Desa International (R165DT) Utility Heater
I have been using my heater for 2 weeks and it is only on the second tankful of fuel. It is producing a lot of smoke when it is running, which it did not do on the first tank of fuel. I am using #2 diesel fuel.
Smoke is an indication of an improper air/fuel mixture, partially blocked nozzle or blocked air passages.
Kerosene must be atomized and mixed with the right amount of air to burn without smoke and odor.
You should consult your manual to have a guide to resolving the issue.
1. Make sure pump pressure is set accurate (5.6 p.s.i.). The pump controls the air/fuel mixture.
2. remove nozzle and clean with brush and compressed air. Also inspect rear of combustion chamber where air flows into and around the chamber to ensure proper air flow. Any materials that may be bent should be replaced. If not formed properly, the air flow through the heater changes as a result.
